The first morph aspect you take is supposed to include the morph's name in it and a short descriptor, and the rules basically say to think of it as being like a High Concept aspect for the morph itself. The two examples given in the rules are 'Scarred Octomorph' and 'Healthy Flat', and to give further examples from my character and ThisOneGal's, I took 'Healthy Pleasure Pod' and she chose 'Original Futura'.
The second aspect is meant to be more of a regular descriptive aspect, and the aspects listed alongside the morphs in the rules are intended as samples for what sort of aspect you might take. For the aspect you're considering, something like 'Just Another Face in the Crowd' or 'A Commonly-Available Face' might be a slightly less awkward-sounding way to get the same sort of aspect.
Any morph can take any morph stunt, technically. The ones they're listed with are just the standard ones they're grown or built with, and any others you choose are after-market modifications your character chose to make.
If you want to emphasize the generic looks of you morph, try a Vacuum Pod: http://i.imgur.com/FumC2ET.png Just throw the 'Environmental Adaptation (Vacuum)' trait on a worker pod.
Based on those stats, I actually think that a better option for working up the stats on a Vacuum Pod would be to add the Worker Pod's traits onto the Bouncer. Just replace the Essential Biomorph Traits with Essential Pod Traits, then add on Common and Stigma (Pod).
Edit: ...And the enhanced respiration probably counts as Environmental Adaptation (Thin Atmosphere), and the light bioweave armor likely counts as the Armor stunt, as it does on the Fury. Man, the Vacuum Pod is basically the Bouncer+ as far as stats go...
